Mike,

I'm not referring to water in the fuel as we deal with in piston
pounders (and where it would be expected to affect a number of
airplanes), but rather the normal moisture entrained in fuel and that
processes through the system without any effect except at high altitude
where it's so terribly cold and the entrained moisture freezes and can
clog filters with the very small ice particles unless something like
PRIST is used. (Although one poster was correct, it usually takes more
than a few minutes to cool the fuel to the point where the entrained
water freezes. It's more of a concern after about an hour at cruise.)

May not be a good theory as it appears the crew let the speed
deteriorate badly in the final climb to 410 and it continued to bleed
off once there.

All the best,
Rick
